I agree with Ollie Onion. I think what it's really important is for the PM to closely monitor the pitch during the flare and to do the standard call out in due time when applicable: >10 degrees for 319/320 or >7.5 degrees for A321.
From the old FCOM, the tail strike value for A321 was at 9.5 degrees and A320 11.5 degrees with the gears fully compressed.
